Research Interests

I use spectroscopic observations of transiting exoplanets to characterize their atmospheres. These observations can reveal the compositions and climates of a set of planets much larger and more diverse than those contained in our own Solar System. My research currently focuses on characterizing hot Jupiters with the Hubble and Spitzer Space Telescopes. As new facilities such as the James Webb Space Telescope allow us to observe smaller planets in more detail, I am interested in using transit spectroscopy to study the habitability of terrestrial exoplanets.
